NASA Shows Off Mock-Up of Mars-Capable Spacecraft
N!NJA writes with this snippet of a report from Reuters: "NASA gave visitors to the National Mall in Washington a peek at a full-size mock-up of the spacecraft designed to carry US astronauts back to the moon and then on to Mars one day. The design of Orion was based on the Apollo spacecraft, which first took Americans to the moon. Although similar in shape, Orion is larger, able to carry six crew members rather than three, and builds on 1960s technology to make it safer."
They're still working on the parachute.
Would that be the large, unmarked banks of blinking square lights, the female voice that always says "Insufficient Data" followed by a dramatic orchestral chord, or the engine that the chief engineer can only repair 10 seconds before destruction?
Rich And Stupid is not so bad as Working For Rich And Stupid.
Don't get me wrong I hope we get off this rock and have a *real* space program but I suspect that I am not the only person reading this that thinks they were born before their time.
Good luck NASA, I hope it all goes well, this time.
My ism, it's full of beliefs.
Current Unixes (Mac OS X, FreeBSD, Darwin, Solaris, etc.) are also a derivative of 1960s technology. And if we were talking about that, the Unix and most of tne Linux guys, at least, would all be saying "yeah, but it's stable because it's so mature."
what's the difference then, with a 1960s Apollo-derived capsule, then?

We'll be at Alpha centuri in a few years, if all goes well.
Nah, I prefer to win the game by global conquest. It's much more entertaining to pour all of your resources into armies, fleets and aircraft than spaceship components. Those fucking Celts will soon pay for sacking Athens back in 3400 BC, muhahahahahahahahaha.
I want peace on earth and goodwill toward man.
We are the United States Government! We don't do that sort of thing.
No, they're replacing the obsolete 1980s technology (shuttles) with modern, 1960s technology. It's progress.
No, no, Progress is Russian:

Return one hour later.
Who's happy to see you?
I (for once) RTFA, and from what I gathered, they've developed this module and updated launcher to provide an effective round trip mechanism for Moon expeditions, where they will practice the operations that will be required when a full scale Mars mission is executed (sometime around between 2020-2030). I think the important point is that NASA is realizing that the shuttle is not an effective mission system for the next generation of Moon missions, which are a pre-req for any future Mars missions.
To me, this actually sounds like a sober assessment - and one that is long overdue.

Is it too much to ask for people who read a supposedly tech site actually read, and perhaps think, before pounding their keyboards with things like "how's that little thing going to get 6 astronauts to Mars?", "NASA is stoopid", and the like?
Its proposed use is to carry up to 6 astronauts to the space station, and from there, 4 to the Moon. For the Moon missions, Orion will travel along with the Altair lunar lander.
For Mars missions, "Orion could rendezvous in low Earth orbit with vehicles that will take explorers to other destinations in our solar system such as Mars." http://www.nasa.gov/pdf/306407main_orion_crew%20_expl_vehicle.pdf
These Mars-bound vehicles will be assembled in low Earth orbit. There is no reason to believe that 4 or 6 astronauts would be confined to the small Orion capsule for the duration of a Mars voyage.
On a side note, I was 5 years old when I watched the first manned landing on the Moon. It's amazing to me that a manned Mars mission may happen when I'm in my 70's. Certainly not how I imagined things when I was young.
No....I think you'll find it *WAS* rocket science.
Indeed, good example. Although lot of the 1960's stuff wasn't exactly rocket science....for example, the Saturn V's had a problem with instabilities building up on the face of the combustion plate due to the pattern of holes that the fuel/oxidiser was sprayed through. In the end they got a bunch of blank combustion plates and drilled holes at random until they found one that worked without blowing the rocket to smithereens....or at least worked for the eight minutes or so that it took to get to orbit.
People forget that the Apollo project killed off the much more reasonable X-plane development, one of which by 1962 was already flying at an altitude of sixty miles. Progression to space travel was seen as the logical next step. But when JFK decided "HOLY FUCK WE GOTTA GO TO THE MOON!", and the developers told him it might be possible to do deep space stuff by the seventies, he opted to kill the project and go for Wernher von Braun's batshit insane rockets instead.
Um, reasonable in what way? It certainly wasn't useful for putting cargo in orbit. The most efficient and practical way (currently) to put anything into space is an engine strapped to gigantic gas tank strapped to a little bit of cargo. Adding additional stuff like wings, landing gears, rudder (and a frame to support it all) only detracts from the amount of cargo you can launch and seems to have negligible reuse benefits as demonstrated by the space shuttle.
For the X-15 series, you might just be right. But the proposed X-20 was the plane that eventually got the chop. This one had a rocket too, which essentially made it a prototype space shuttle. Reusable. What's more, the Titan rockets they wanted for it had 2.5 million pounds of thrust (11,100,000 force newtons) compared with the Mercury-Atlas' 367,000 (1,600,000). What made them cut the project was that the Atlas rockets were already available whereas the more powerful Titan rockets were still four years away.
